Yep, that did it... :)
On a side note, these might also show up in Coverity if that goes
through... A more permanent fix than disabling the warnings and strict
aliasing might be better in the long run.
Could some of these aliasing conflicts be avoided by using unions?
int xxx;
typedef union {
int x;
float y;
} test;
...
test * t = (test *)x;
x = t->x;
float y = t->y;
That piece of code does not produce any more warnings, and I *think*
it does the same thing...
